am i the only one who suffering this problem ??
i can't imagine that the developers and the specialists all over the whole world couldn't solve this f***** problem ??
is it possible !! this little problem marked unsolvable !!
after three days of continuous search for 24 hours looking for reasonable solution ?? till now neither me nor the other people who suffering just like me found the solution .
well i'll explain the problem i hope i could find reasonable answers from those beautiful minds :
my phone is galaxy s2 plus
when i connect the device to the laptop , the laptop recognize it . OK ? just concentrate
this leads us to conclude that all drivers are installed and updated and the usb port of the laptop works properly and the usb port of the phone is working properly too also this means that usb cable is good DO YOU AGREE WITH ME ?
so PLEEEEEASE DO NOT TELL ME TO CHECK ONE OF THOSE i have already checked them
now when i try to go to to download mode i should turn off the phone as all of you know as the device turns off, a small box at the corner of laptop appears telling me that the last device you connected malfunctioned and the computer doesnt recognize it . so how should i enter the f****** download mode if the laptop doesnt recognize the f****** phone i checked the device manger there is yellow triangle (at the same site where the device had been recognized before turning off ) unknown device "device descriptor request failed".
it seems normal for you cuz you think now in the recovery mode what if i told you that i have flashed wrong cwm recovery and now i am not capable of entering recovery .

Do you check the USB/ANDROID debugging mode is on or not?
If not ON , you turn ON it. And then try again
I experienced this with win 8 and win 10. You need to go to device manager and disable USB root hub.
Connect your device to the computer in flash mode. The computer will say “USB Device Not Recognized”.
Go to Device Manager and you will see your device listed as “Unknown USB Device (Device Descriptor Request Failed)” in “Universal Serial Bus controllers” section
Now in “Universal Serial Bus controllers” section you should also have “USB Root Hub”’s (might be several of them). Click through them and find the one that has “Unknown USB Device (Device Descriptor Request Failed)” in the “Power” tab (should be next to General).
Right click on that “USB Root Hub” and press “Disable”. Now you should have a small arrow pointing down on the USB Root Hub icon and the “Unknown USB Device (Device Descriptor Request Failed)” should have disappeared.

After you are done, don't forget to enable it back.

hi. i'm having problem in connecting my device in bootloader..
i used to be able to connect with PDAnet in bootloader without any problem, but now all i have is "connecting to your phone". I've downloaded the USB driver package from the sdk but still no luck..
any idea ?
*yes i search the XDA forum and try following the guides but i still have no luck*
have you tried the connection on another computer?
sometimes the computer USB ports tends to go crazy and wont work with the device no matter what
there's an utility (forgot the name) that lets you delete all the bugged USB associations in the PC
if you can find that, then you can try it as well

I give this answer a lot: Try another cable. One of the data connections has broken, which lets you still charge but breaks the USB I/O.

The pc doesn't recongnise it on device manager (i have a win 7 pc), the phone however react as pluged in a charger.
their is no mtp or mass storage switch on notification.
i have reinstall the driver of samsung several times with smart switch & also made it manual by suppressing directrly the samsung usb driver from programs on control panel then reinstall it but no hope.
I can't figure out eitheir its hard or soft.
i had change my cable & also test my pc with another Galaxy s6 it works fine, but mine no.
i have made wipe cache / factory reset also made an initialisation from parameters the phone is formated but not recognised by the pc also test it on another pc but the same behaviour windows pcs doesn't recognise my phone.
However, i figure out that when its on the restore mode (volume down + lock + home) the pc recognise it by Odin and smart switch.
i install the same rom on it also made an emergency restore with S/N and model and the process completes fine with smart switch and i saw the donwload progress bar completing on my phone.
but still i m stuck its not recognised please help !!!
i tries to use *#0808# and its on AP / MTP + ADB but no hope
i plug it on ADB android studio but the device list is empty :'(

i used different cables and pcs but still not recognised
yesterday i used odin with those options :
BL/AP/CP/CSC and checked
Auto-reboot
F.reset Time
phone EFS Clear
Phone bootloader update
it has taking some while to execute but after that my phone was working and detectable again by my pc the problem was resolved for a couple of hours, in the evening the problem occured again.
and i have tried the process again the same why but no connection at all.
i don't know if its a hardware problem or software related problem
because the usb work when i m in restore mode (Odin mode) otherwise no.
Its an advance problem i already check all about usb / cable and pcs related problem.
Problem resolved
I sent my S6 to Samsung SAV it take them 4 days.
they doesn't give me proper answers on what they have done but i saw that my mini-usb plug is new so i expect that they got this part changed accrodingly the samsung has no sign of damage its a clean operation.
Its now detectable. It was indeed a Hardware problem
i have the same issue but in a g928f
today i changer my lcd with the micro usb flex
so all is new except the main board and still is not recognised at any pc with any cable.
i am really starting to feel very sorry for this phone.
odin does not see it at all even at download mode.
i don't know what else to do.
Software or Hardware Issue
I have a s6 920t that I am suppose to pay for at the end of the day. I got it from a friend who bought it while overseas. The only time my computer detects it is in download mode/odin mode, I hear the sound and I see it as "Added". When I try to connect any other way I don't hear the sound my laptop makes when it has detected a new device also otg cables don't work. I just simply want to know if this a software or a hardware issue? Software I can fix but if it is hardware I don't want to waste my money. Please anyone reply as soon as you can so I can decide what to do.
Thank you
I have two S6 Edge and one of them started doing this (phone only appears on USB when in Download mode). When swapping the motherboard between the phones, it works. So the problem isn't with the motherboard, but the USB connection module attached with the ribbon cable... There must be a chip on the module which gets locked somehow and replacing the board is at least one way to fix it. Hopefully someone finds another method without replacing the charger board?
Hi guys, i'm getting this problem and cant connect to pc and i think i've tried it all.
when i connect my phone to the PC, it stars charging but my pc doesn't recognize the device, and my phone doesn't show the notification to make it file transfer.
Could it be a computer issue?
it seems not, i've uninstalled and installed drivers (ADB and Fastboot, oneplus drivers, google drivers) and the problem persist, and even try it on another computer and its the same, the phone does not appear even on Device Manager.
Could it be the Cable?
I don't think so, i'm using the original oneplus cable, it use to work really well before, and i have even connect other phone with the same cable and the other phone is recognize by the computer, so it''s not a cable issue... but I still when to a Tech-store and try other USB-C cables with their computer but my issue still persist (phone isn't recognize, just charge).
Could it be a phone software issue?
Maybe? but i discover this issue 3 weeks ago and a i was on EVOX rom and i thought it would be solved flashing another rom, and i CLEAN FLASH Resurrection Remix Rom, but then the problem was still there!
cant connect even on FASTBOOT MODE...
BTW, before installing RR, i Installed OOS 10.3.4, and still my computer doesnt recognize the phone, YES i have enabled developer options and USB debugging is enabled, and USB PREFERENCES to File transfer, but its not helping me, the "usb for" option its all grayed out and cant change that.
Right now i'm stuck on a RR build without Gapps, and i lost ROOT and RECOVERY, and as you may think, i cant install any of them because i cant connect to my pc, so i'm in a pretty difficult situation here hehe, could you please help me out?
This helped me. Hope it works for you too

Thanks for your reply, but this didn't work because my device isn't shown on device & printers, or anywhere as far as i checked...
PROBLEM SOLVED.
I think this is the silliest solution I've ever seen, it was just DUST, i clean my USB-C PORT (with a mask xD) and then pluggin, AND VOILA, it worked!!! so keep your ports clean everyone
